Die Erfindung betrifft einen Sitz für ein Kraftfahrzeug, insbesondere für einen Personenkraftwagen.The invention relates to a seat for a motor vehicle, in particular for a passenger car.

Ein derartiger, der DE 38 01 294 A1 entnehmbarer Beifahrersitz für einen Omnibus umfaßt karosseriefeste vordere Gestellbeine, an denen ein Sitzelement schwenkbar angelagert ist. Außerdem ist ein Lehnenelement schwenkbar am Sitzelement gelagert. Um den Eingangsbereich des Omnibusses zum Ein und Ausstieg freigeben zu können, ist der Sitz zwischen einer Verriegelungsposition, in welcher das Sitzelement und das Lehnenelement zum ordnungsgemäßen Sitzen verwendbar sind, und einer Entriegelungsposition verstellbar, in welcher das Sitzelement und das Lehnenelement im Fahrzeug bezüglich der Fahrtrichtung nach vorn verstellt sind. Um die Vorverlagerung des Sitzes zu erleichtern, sind zwischen den vorderen Gestellbeinen und dem Sitzelement Dämpfermittel in Form von Gasdruckfedern vorgesehen. Bei der Rückverlagerung des Sitzes von seiner Entriegelungsposition in seine Verriegelungsposition wirken diese Dämpfermittel der Rückstellbewegung des Sitzes entsprechend dämpfend entgegen.Such, the DE 38 01 294 A1 removable front passenger seat for a bus includes body-mounted front frame legs, where a seat element is pivotally attached. Furthermore a backrest element is pivotally mounted on the seat element. Around the entrance area of the bus to get in and out being able to release is the seat between one Locking position in which the seat element and the Backrest element are used for proper sitting, and an unlocking position adjustable, in which the Seat element and the backrest element in the vehicle with respect to Direction of travel are adjusted forward. To the forward displacement To facilitate the seat are between the front Frame legs and the seat element damper means in the form of Gas springs provided. When relocating the seat from its unlocked position to its locking position act these damper means the return movement of the seat correspondingly dampening.

Da bei diesem bekannten Sitz sowohl die Rückenlehne als auch das Sitzelement verlagert und in der entsprechenden Stellung lagegesichert werden müssen, ist ein aufwendiger Verriegelungsmechanismus für die Rückenlehne und das Sitzelement nötig. Ein solch komplexer Verriegelungsmechanismus erfordert einen relativ hohen Bedien- und Kontrollaufwand, beispielsweise zur Sicherstellung, ob der Sitz in der Gebrauchsstellung ordnungsgemäß verriegelt ist.As in this known seat, both the backrest and displaced the seat element and in the appropriate position must be secured, is a complicated Locking mechanism for the backrest and the Seat element needed. Such a complex locking mechanism requires a relatively high operating and monitoring effort, for example, to ensure that the seat in the Operating position is properly locked.

Ein weiterer, ähnlicher Sitz ist aus der US 5 224 750 A bekannt. Another similar seat is known from US 5,224,750 A.

Aus der GB 940 100 A ist ein Sitz bekannt, bei dem die Rückkehr von der Entriegelungsposition in die Verriegelungs position nur in der Endphase durch ein elastisches Element gedämpft wird.From GB 940 100 A a seat is known in which the return of the unlocking position in the locking position only in the final phase is damped by an elastic element.

Aus der DE 41 36 363 A1 ist ein Rücksitz für ein Kraftfahrzeug bekannt, der aus einer Gebrauchsstellung in eine Nichtgebrauchsstellung bewegbar ist. Hierzu wird das Sitzelement um eine am entfernt von der Rückenlehne liegenden Ende angeordnete Schwenkachse verschwenkt, bevor die Rückenlehne um eine in deren unterem Bereich vorgesehene Schwenkachse in eine waagerechte Lage gebracht werden kann. Das Sitzelement und die Rückenlehne sind über Gasdruckfedern miteinander verbunden, die den Bewegungen des Sitzes von der Gebrauchsstellung in die Nichtgebrauchsstellung - und umgekehrt - dämpfend entgegenwirken.From DE 41 36 363 A1 is a back seat for a motor vehicle known from a position of use in a Non-use position is movable. This is the Seat element at one on the remote from the backrest End arranged pivot axis pivoted before the Backrest around one provided in the lower area Swivel axis can be brought into a horizontal position. The Seat and back are over gas springs connected to each other, the movements of the seat of the Use position in the non-use position - and vice versa - counteract dampening.

Schließlich ist aus der DE 39 34 171 C2 sowie aus der DE 38 13 594 A1 ein Sitz bekannt, der ein Sitzelement und ein daran gelagertes Lehnenelement aufweist. Üblicherweise ist ein derartiger Sitz außerdem mit einem Basiselement ausgestattet, das im Kraftfahrzeug befestigbar ist und an dem das Sitzelement gelagert ist. Die bekannten Sitze sind zwischen einer Verriegelungsposition und einer Entriegelungsposition verstellbar, wobei in der Verriegelungsposition das Sitzelement und das Lehnenelement für einen Fahrzeuginsassen zum ordnungsgemäßen Sitzen verwendbar sind, während in der Entriegelungsposition das Lehnenelement im Fahrzeug bezüglich der Fahrtrichtung soweit nach vorn verstellt ist, daß ein bezüglich der Fahrtrichtung hinter dem Sitz angeordneter Raum, z.B. der Fondraum, zum Beladen bzw. Entladen, insbesondere zum Einsteigen bzw. Aussteigen von Fondinsassen, zugänglich ist. Um den Sitz zwischen seiner Verriegelungsposition und seiner Entriegelungsposition verstellen zu können, ist hierbei das Lehnenelement am Sitzelement schwenkgelagert.Finally, from DE 39 34 171 C2 and DE 38 13 594 A1 a seat known, a seat element and a having stored backrest element. Usually one is such seat also equipped with a base element, which can be fastened in the motor vehicle and on which the seat element is stored. The known seats are between one Locking position and an unlocking position adjustable, wherein in the locking position, the seat element and the back element for a vehicle occupant to proper seats are usable while in the Entriegelungsposition the backrest element in the vehicle with respect the direction of travel is adjusted so far forward that a space arranged behind the seat with respect to the direction of travel, e.g. the rear compartment, for loading or unloading, especially for Getting in or out of rear passengers, is accessible. Around the seat between its locking position and its To be able to adjust unlocking position, this is the Backrest element pivotally mounted on the seat element.

Bei den zuletzt genannten Sitzen sind zwischen dem Lehnenelement und dem Sitzelement Federmittel in Form eines elastischen Bauteiles angeordnet, insbesondere ein weichelastischer Puffer bzw. ein als Gummiteil oder Weichplastikteil ausgebildetes druckelastisches Elastomerteil. Diese Federmittel dienen dazu, in der Verriegelungsposition des Sitzes das Lehnenelement gegenüber dem Sitzelement derart zu verspannen, daß Relativbewegungen zwischen diesen Elementen und somit eine Geräuschentwicklung verhindert wird.In the latter seats are between the Backrest element and the seat element spring means in the form of a arranged elastic member, in particular a soft elastic buffer or as a rubber part or Soft plastic part trained pressure elastic elastomer part. These spring means serve in the locking position of the Seat the backrest element relative to the seat element so tense that relative movements between these elements and thus noise is prevented.

Aufgabe der vorliegenden Erfindung ist es, unter Beibehaltung der komfortabel gedämpften Rückverstellung des Sitzes den Bedienungsaufwand bei der Zurückverlagerung des Sitzes in seine Verriegelungsposition zu reduzieren.Object of the present invention is, while retaining the comfortably damped return adjustment of the seat Operating effort in the relocation of the seat in his Reduce locking position.

Diese Aufgabe wird erfindungsgemäß durch einen Sitz mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen mit zweckmäßigen Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a seat with the Characteristics of claim 1 solved. advantageous Embodiments with expedient developments of Invention are specified in the subclaims.

Bei dem Sitz nach der Erfindung wird dessen Rückstellbewegung zur Komfortsteigerung während einer Endphase bis zum Erreichen der Verriegelungsposition gedämpft. Durch diese Maßnahme wird während der Sitzrückverstellung die kinetische Energie des Sitzes in Reibungs- bzw. Wärmeenergie umgewandelt, wobei die Dämpfungswirkung, d.h. die der Rückstellbewegung entgegenwirkenden Dämpferkräfte von der Geschwindigkeit der Rückstellbewegung abhängen, so dass höhere Rückstellgeschwindigkeiten entsprechend größere Dämpferkräfte zur Folge haben. Die entsprechenden Sitzbauteile, z.B. ein Verriegelungsmechanismus, werden dadurch geschont; insbesondere kann dadurch auch die Betriebssicherheit des Fahrzeuges verbessert werden. Je größer die Endphase der Rückstellbewegung, d.h. der durch die Dämpfermittel gedämpfte Anteil des Rückstellweges, desto kleiner ist die kinetische Energie des Sitzes und um so besser kann ein schwungvolles Einschlagen des Sitzes in seine Verriegelungsposition durch die erfindungsgemäßen Dämpfermittel verhindert werden.In the seat according to the invention whose return movement to increase comfort during a final phase to reach damped the locking position. This measure will during seat recapture the kinetic energy of the Seat converted into frictional or thermal energy, the Damping effect, i. the return movement counteracting damper forces on the speed of the Depend on return movement, so higher Resetting speeds corresponding to larger damper forces have as a consequence. The corresponding seat components, e.g. one Locking mechanism, thereby being spared; especially can thereby also the operational safety of the vehicle be improved. The larger the final phase of the Return movement, i. the steamed by the damper means Proportion of the return path, the smaller is the kinetic Energy of the seat and the better a lively Impact of the seat in its locking position by the Damper means according to the invention can be prevented.

Darüber hinaus sind bei dem Sitz nach der Erfindung die Dämpfermittel so dimensioniert, daß sich der Sitz bei der Rückstellbewegung aufgrund seiner Gewichtskraft selbsttätig in seine Verriegelungsposition verstellt. Hierdurch verringert sich der Bedienungsaufwand des Sitzes, da eine Kontrolle des Fahrgastes, ob der Sitz seine verriegelte Gebrauchsstellung erreicht hat, entfällt. Dies ist insbesondere dann von Bedeutung, wenn der Sitz über eine selbsttätig arbeitende Verriegelungseinrichtung verfügt, die den Sitz sichert, sobald dieser seine Verriegelungsposition erreicht.Moreover, in the seat according to the invention, the Damper means dimensioned so that the seat at the Return movement due to its weight automatically in adjusted its locking position. This reduces the operating effort of the seat, as a control of the Passenger, whether the seat its locked use position achieved, is eliminated. This is especially true of Meaning if the seat has an automatic working Locking device which secures the seat as soon as this reaches its locking position.

Entsprechend einer bevorzugten Ausführungsform können die als Kolben-Zylinder-Aggregat ausgebildeten Dämpfermittel als Gasdruckfeder oder Öldruckdämpfer ausgebildet sein. Mit Hilfe derartiger, an sich bekannter Dämpfermittel kann die gedämpfte Endphase der Rückstellbewegung besonders groß ausgebildet werden. Darüber hinaus sind derartige Dämpfermittel relativ preiswert, haben sich in der Praxis bewährt und sind relativ einfach für die am Sitz zu beherrschenden Kräfte auslegbar.According to a preferred embodiment, the designed as a piston-cylinder unit damper means as a gas spring or oil pressure damper be educated. With the help of such, known per se Damper means the damped final phase of the return movement be made particularly large. In addition, are Such damper means are relatively inexpensive, have in the Proven practice and are relatively easy for those on the seat too dominant forces interpretable.

Bei einer Weiterbildung des erfindungsgemäßen Sitzes können Verriegelungsmittel vorgesehen sein, die den Sitz bei Erreichen seiner Verriegelungsstellung selbsttätig verriegeln. Diese Verriegelungsmittel können dann einen Schwenkbügel aufweisen, der zwischen einer Halteposition, in der er mit einem Bügelteil einen durch die Verstellbewegung des Sitzes zwischen dessen Verriegelungsposition und Entriegelungsposition zwangsläufig mitverstellten Vorsprung übergreift, und einer Freigabeposition um eine Schwenkwelle schwenkverstellbar ist, in der er den Vorsprung freigibt. Die in diesem Fall als Kolben-Zylinder-Aggregat ausgebildeten Dämpfermittel können sich dann zum Dämpfen der Rückstellbewegung zwischen dem Bügelteil des in seiner Freigabeposition befindlichen Bügels und der Schwenkwelle hindurcherstrecken und am Vorsprung abstützen. Durch diese Vorschläge ergibt sich eine kompakte Bauweise, die außerdem günstige Hebelverhältnisse für die Krafteinleitung des Dämpfers ermöglicht.In a further development of the seat according to the invention can Locking means may be provided which the seat upon reaching lock its locking position automatically. These Locking means may then have a swivel bracket, the between a holding position, in which he with a strap part one by the adjusting movement of the seat between the Locking position and unlocking position inevitably mitverstellten projection overlaps, and a release position is pivotally adjustable about a pivot shaft, in which he Lead releases. The in this case as piston-cylinder aggregate trained damper means can then for Steaming the return movement between the temple part of in his release position located bracket and the Pass the pivot shaft and support it on the projection. These proposals results in a compact design, the In addition, favorable leverage for the introduction of force of Damper allows.

Durch die Rückstellbewegung des Sitzes 1 bzw. hier des Lehnenelmentes 5 wird das Dämpfermittel 9 von einem Anfangszustand, in dem seine Kolbenstange 12 maximal ausgefahren ist, in einen Endzustand verstellt, in dem die Kolbenstange 12 maximal eingefahren ist. Die Dämpfermittel 9 können hier nicht dargestellte Federmittel aufweisen bzw. mit Federmitteln zusammenwirken, deren Federkräfte parallel zu den Dämpferkräften der Dämpfermittel 9 wirken, wobei die Federmittel mit den Dämpfermitteln 9 gekoppelt sind, derart, daß die Federmittel die Dämpfermittel 9 in deren Anfangszustand vorspannen.By the return movement of the seat 1 or here of the Lehnenelmentes 5, the damper means 9 of a Initial state in which its piston rod 12 maximum is extended, adjusted to a final state in which the Piston rod 12 is retracted maximally. The damper means 9 can have here not shown spring means or with Spring means cooperate, the spring forces parallel to the Damper forces of the damper means 9 act, the Spring means are coupled to the damper means 9, so that the spring means the damper means 9 in its initial state Pretension.

Entsprechend den Fig. 2 und 3 wird bei einer anderen Ausführungsform des erfindungsgemäßen Sitzes 1 ebenfalls das Lehnenelement 5 gegenüber dem Sitzelement 4 verschwenkt, um den Sitz 1 zwischen seiner in Fig. 2 dargestellten Verriegelungsposition und seiner in Fig. 3 dargestellten Entriegelungsposition zu verstellen. Zur Schwenklagerung des Lehnenelementes 5 ist dieses mit einem entsprechenden Beschlagteil 13 ausgestattet, das bei 7 am Sitzelement 4 schwenkgelagert ist. Am Beschlagteil 13 ist in einem vom Lager 7 abgewandten Bereich ein entgegen der Fahrtrichtung fingerartig abstehender Vorsprung 14 ausgebildet, der einen Teil einer Verriegelungseinrichtung des Sitzes 1 bildet. Der Vorsprung 14 wirkt zum Verriegeln des Sitzes 1 bzw. des Lehnenelementes 5 in der Verriegelungsposition mit einem Schwenkbügel 15 zusammen, derart, daß ein Bügelteil 16 des Schwenkbügels 15 den Vorsprung 14 übergreift, wobei der Schwenkbügel 15 eine Halteposition einnimmt.Referring to Figs. 2 and 3 is at another Embodiment of the seat 1 according to the invention also the Back element 5 pivoted relative to the seat member 4 to the Seat 1 between his in Fig. 2 shown Locking position and its in Fig. 3 shown To adjust the unlocking position. For pivotal mounting of the Backrest element 5 is this with a corresponding Fitting part 13 equipped at 7 on the seat element. 4 pivoted. The fitting 13 is in one of the camp 7 facing away from the direction of travel finger-protruding projection 14 is formed, the one Part of a locking device of the seat 1 forms. Of the Projection 14 acts to lock the seat 1 or the Backrest element 5 in the locking position with a Swivel bracket 15 together, such that a bracket portion 16 of the Swivel bracket 15, the projection 14 overlaps, wherein the Swivel bracket 15 assumes a holding position.

Zur Freigabe des Sitzes 1 bzw. des Lehnenelementes 5 wird der Schwenkbügel 15 um eine Schwenkwelle 17 in eine in Fig. 3 wiedergegebene Freigabeposition schwenkverstellt.To release the seat 1 and the backrest element 5 is the Swivel bracket 15 about a pivot shaft 17 in a in Fig. 3rd pivoted reproduced release position.

Bei dieser Ausführungsform ist das Dämpfermittel 9 besonders raumsparend angeordnet. Die Kolbenstange 12 des als Dämpfermittel wirkenden Kolben-Zylinder-Aggregates 9 erstreckt sich zwischen der Schwenkwelle 17 und dem Bügelteil 16 hindurch, solange der Schwenkbügel 15 seine Freigabeposition einnimmt. Während der Rückverstellung des Sitzes 1 bzw. des Lehnenelementes 5 kommt der Vorsprung 14 mit dem axial freien Ende der Kolbenstange 12 in Kontakt, so daß sich das Lehnenelement 5 am Dämpfermittel 9 abstützen kann. Die Kontaktstelle zwischen Kolbenstange 12 und Vorsprung 14 ist vorzugsweise so gewählt, daß das Lehnenelement 5 in dieser Phase der Rückstellbewegung noch keine allzu große kinetische Energie aufgenommen hat, so daß vom Dämpfermittel 9 keine besonders großen Kräfte aufgenommen werden müssen. Das Dämpfermittel 9 ist dabei so dimensioniert, daß die Gewichtskraft des Sitzes bzw. hier des Lehnenelementes 5 ausreicht, um die Rückstellbewegung bis zur Verriegelungsposition durchzuführen. Während dieser Rückstellbewegung fährt die Kolbenstange 12 in das beispielsweise als Gasdruckfeder ausgebildete Dämpfermittel 9 ein. Sobald der Sitz 1 bzw. das Lehnenelement 5 die Verriegelungsposition erreicht, bewirken nicht dargestellte Bestandteile der Verriegelungseinrichtung ein selbsttätiges Verschwenken des Schwenkbügels 15 in dessen Halteposition, um die Verriegelungsposition des Sitzes 1 formschlüssig zu sichern.In this embodiment, the damper means 9 is special arranged to save space. The piston rod 12 of the Damper-acting piston-cylinder unit 9 extends between the pivot shaft 17 and the bracket part 16th through, as long as the swivel bracket 15 its release position occupies. During the return adjustment of the seat 1 or the Lehnenelementes 5 comes the projection 14 with the axially free End of the piston rod 12 in contact, so that the Backrest element 5 can be supported on the damper means 9. The Contact point between the piston rod 12 and projection 14 is preferably chosen so that the backrest element 5 in this Phase of the return movement is not too big kinetic Energy has absorbed, so that the damper means 9 no particularly large forces must be included. The Damper means 9 is dimensioned so that the Weight of the seat or here the backrest element. 5 is sufficient for the return movement to the Perform locking position. During this Return movement moves the piston rod 12 in the For example, designed as a gas spring damper means. 9 one. Once the seat 1 and the backrest element 5 the Locking position achieved, cause not shown Components of the locking device an automatic Swiveling the swivel bracket 15 in its holding position to the locking position of the seat 1 to form fit to back up.

Solange sich der Vorsprung 14 außerhalb des Schwenkbügels 15 befindet, kann sich die Kolbenstange 12 zwischen Schwenkwelle 17 und Bügelteil 16 erstrecken, wodurch der Schwenkbügel 15 in seiner Freigabeposition gesichert ist.As long as the projection 14 outside of the pivot bracket 15th is located, the piston rod 12 between the pivot shaft 17 and bracket 16 extend, causing the pivot bracket 15 in its release position is secured.
